Solve for f
f=\frac{6}{11}+\frac{130}{11n}
n\neq 0
Solve for n
n=-\frac{130}{6-11f}
f\neq \frac{6}{11}

55nf=30n+650
Swap sides so that all variable terms are on the left hand side.
\frac{55nf}{55n}=\frac{30n+650}{55n}
Divide both sides by 55n.
f=\frac{30n+650}{55n}
Dividing by 55n undoes the multiplication by 55n.
f=\frac{6}{11}+\frac{130}{11n}
Divide 30n+650 by 55n.
30n+650-55nf=0
Subtract 55nf from both sides.
30n-55nf=-650
Subtract 650 from both sides. Anything subtracted from zero gives its negation.
\left(30-55f\right)n=-650
Combine all terms containing n.
\frac{\left(30-55f\right)n}{30-55f}=-\frac{650}{30-55f}
Divide both sides by 30-55f.
n=-\frac{650}{30-55f}
Dividing by 30-55f undoes the multiplication by 30-55f.
n=-\frac{130}{6-11f}
Divide -650 by 30-55f.
